Background: Gastric electrical stimulators (GESs) have been used to treat refractory gastroparesis in patients who fail initial therapies such as dietary modifications, control of psychological stressors and pharmacologic treatment. More recently, gastric peroral endoscopic pyloromyotomy (G-POEM) has emerged as a novel endoscopic technique to treat refractory gastroparesis. We present a case series of patients with refractory gastroparesis who failed treatment with an implanted GES that were safely treated with G-POEM performed under fluoroscopy as a salvage therapy...

BACKGROUND: The reproducibility of gastric emptying (GE) measured with scintigraphy in patients is poorly understood. Our aims were to assess the intra and inter-individual reproducibility of these parameters in patients with upper gastrointestinal symptoms. METHODS: Sixty patients (21 diabetics, 39 non-diabetics) with upper gastrointestinal symptoms underwent scintigraphic-assessment of GE of a solid meal (296 kcal, 30% fat) over 4 hours on two occasions at an average interval of 15 days...

PURPOSE: A retrospective study of 197 patients was performed to evaluate utility of simultaneous fingerstick glucose monitoring during standardized solid meal gastric-emptying scintigraphy (GES). We hypothesized the unlabeled carbohydrate components of the standardized meal often empty at different rates than the labeled egg protein component and that simultaneous glucose monitoring may identify rapid carbohydrate gastric emptying. METHODS: Patients were classified as normal, rapid, or delayed gastric emptying from the standardized solid egg meal GES criteria...

OBJECTIVE: Chronic inflammation in HIV-infected individuals drives disease progression and the development of comorbidities, despite viral suppression with combined antiretroviral therapy. Here, we sought evidence that vagal dysfunction, which occurs commonly as part of HIV-associated autonomic neuropathy, could exacerbate inflammation through gastrointestinal dysmotility, small intestinal bacterial overgrowth (SIBO), and alterations in patterns of soluble immune mediators. DESIGN: This is a cross-sectional observational study...

INTRODUCTION: Upper digestive symptoms may be present in up to 50% of patients with primary Sjögren syndrome (pSS). We report a retrospective cohort of gastroparesis in a population of pSS presenting unexplained dyspepsia. Delayed gastric emptying was defined by a gastric emptying time above 113min or by a retention percentage at 4h more than 10% on scintigraphy. RESULTS: Eleven patients with primary Sjögren syndrome and gastroparesis were included in a retrospective study...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has increased in popularity in recent years as a definitive bariatric procedure. Despite its growing popularity worldwide, the surgical technique is not well standardized. There is a lack of evidence on the matter of the antrum size and its relation to gastric emptying and weight-loss outcomes. The aim of the study is to evaluate the influence of antrum size over gastric emptying and weight-loss outcomes. METHODS: Twenty-five patients were prospectively randomized according to the distance between the first firing and the pylorus: AR group (antrum resection-2 cm from the pylorus) and AP group (antrum preservation-5 cm from the pylorus)...

In this review article important and frequently used investigation methods for gastrointestinal functional diagnostics are presented. Some other rarely used special investigations are also explained. The hydrogen breath test is simple to carry out, ubiquitously available and enables the detection of lactose, fructose and sorbitol malabsorption. Furthermore, by the application of glucose, the test can be carried out when there is a suspicion of abnormal intestinal bacterial colonization and using lactulose for measuring small intestinal transit time...

Background: Patients with symptoms suggestive of gastroparesis exhibit several symptoms, such as epigastric pain, postprandial fullness, bloating and regurgitation. It is uncertain if such symptoms reflect underlying oesophageal motor disorder. Aims: To examine whether patients with epigastric pain and postprandial distress syndrome suggestive of functional dyspepsia and/or gastroparesis also have concomitant oesophageal motility abnormalities and, if so, whether there are any associations between these disturbances...

Impaired fundic accommodation (FA) limits fundic relaxation and the ability to act as a reservoir for food. Assessing intragastric meal distribution (IMD) during gastric emptying scintigraphy (GES) allows for a simple measure of FA. The 3 goals of this study were to evaluate trained readers' (nuclear medicine and radiology physicians) visual assessments of FA from solid-meal GES; develop software to quantify GES IMD; and correlate symptoms of gastroparesis with IMD and gastric emptying. Methods: After training to achieve a consensus interpretation of GES FA, 4 readers interpreted FA in 148 GES studies from normal volunteers and patients...

REVIEW
Allen A Lee, William L Hasler
Longstanding diabetes mellitus (both type 1 and type 2) can impair gastric motor function and cause significant upper gastrointestinal symptoms which significantly degrade quality of life, cause nutritional deficits, and degrade healthcare resource use. The most commonly considered gut complication of diabetes, diabetic gastroparesis, is a syndrome of delayed gastric emptying in the absence of mechanical obstruction which leads to symptoms of nausea, vomiting, postprandial fullness, early satiation, bloating, and upper abdominal pain...

Aprepitant, an NK1 receptor antagonist, is approved for the treatment of chemotherapy-induced or postoperative emesis by blocking NK1 receptors in the brain stem vomiting center. The effects of NK1 receptors on gastric functions and postprandial symptoms in humans are unclear; a single, crossover study did not show a significant effect of aprepitant on gastrointestinal transit. Our aim was to compare, in a randomized, double-blind, placebo-controlled, parallel-group study (12 healthy volunteers per group), the effects of aprepitant vs...
